Overtemperature protection Above a temperature of approx. 75°C on the power board the power part of the controller switches off and the error bit is set (see objects 1001h and 1003h). After cooling down and confirming the error (see table for the controlword, "Fault reset"), the controller again functions normally. The following temperature test results provide information on the temperature behavior of this controller. Temperature tests are performed under the following conditions: Operating voltage: 24 V DC Motor current: 3 A (CL4-E-1-xx low current)/6 A (CL4-E-2-xx high current) rms Operation mode: Velocity Mode, full step, 30 rpm Ambient temperature: 25 °C / 45 °C Altitude of site: 500 m above sea level No external cooling in the climatic chamber, e. g., via fan The following graphics show the results of the temperature tests: Note: Aside from the motor, the exact temperature behavior is also dependent on the flange connection and the heat transfer there as well as on the convection in the application. For this reason, we recommend always performing an endurance test in the actual environment for applications in which current level and ambient temperature pose a problem.
